Magic Nikonian ViewFinder

I just purchased the app since I’ve read that I can use sticky value in premium option. I would to know how I can add new value, for example 600mm and then use it by tap ? After payment my app looks like the same without changes in (focal length) value area. Thanks!

To whom it may concern . This app looks like a solid app, one issue is that Nikon keeps on doing what they think people want since it runs in their culture there way of those thoughts.The D500 and D850 are not what you think they are especially the D500. In actuality it is the lens size out of the back of it which controls the amount of light that is imprinted on a sensor. That's why the tamron 10-24 mm f3.5 to 4.5 is a true dx lens . Especially designed for the D500

October 20, 2018 Update I have now been using this app for three months and I have to say it’s been a great help for someone who knew nothing about using a DSLR. Their is still a lot I need to lean, but this has been a great help. But for a beginner it would be nice if you could set in a shutter speed and then your ipad would darken or brighten indicating if you are over exposed or underexposed. But the more you explore your camera settings and practice taking photo the more you will lean what shutter speed iso and aperture you need. Also I hope it’s ok to mention another app that has been a great help to me and it is called Cascable but it’s more of a remote and learning tool. It’s great if you want to use a tripod and long exposures. July 19, 2018 I’m new at photography and came across this app so I decided to give it a try. Still not sure what I’m doing. I have a Nikon D7100 and trying to learn how to use the camera other than in auto mode. But from what I can tell is, and I might be wrong but I set the app to dxxxx because i have a D7100 I put in the lens I’m using and it show me the depth of field and you put in how far you are from the subject you snap a picture on your iPhone and it saves that information on the photo so you can set your camera to the same settings. If you shoot a picture on your iPhone at 300mm its blurry but the one you take with the Nikon should be in focus. I’m just learning my camera so I will update after I use this app a little more. So far I think it’s a great learning tool.
